What devices support the Foundation Models framework?

It requires Apple Intelligence-enabled hardware such as iPhone 15 Pro or newer, and M1+ iPads and Macs running iOS/macOS 26 or later.

Can I use this for general knowledge queries like ChatGPT?

No, the on-device 3B model is specifically optimized for tasks like summarization and classification rather than broad world knowledge.

Does this require an internet connection?

No, one of the primary benefits is that all inference is performed entirely on-device, ensuring privacy and offline functionality.

How does this skill handle context limits?

The skill provides guidance on checking input length and proactively trimming content to avoid context overflow and silent failures.

What is the benefit of using @Generable?

The @Generable macro provides type-safe structured output, ensuring the model's response matches your Swift structs exactly for easier data handling.
